Hi Dave Meanwhile, given the high frequency of video problems (ahah, a pun!) I have restarted a project from 2013 to produce an improved video output that is much friendlier to converters and upscalers. Oooh - will that be based on Nasta's earlier exposition on the 8301 and the potential to toggle t...

Hi Papanillu If you want to validate the advice given thus far, you might want to see whether using the composite monochrome output fed to your VGA upscaler renders a solid - albeit grey-scale - image where you currently see the blue/red unstable stripes.

I do not believe that there is a list of known issues waiting to be addressed by some enthusiastic soul, although at least one suggestion was posted a while back to default the IPC Interrupt to disabled (which can be done...

Hi everyone In case you haven't been following the recent thread on the QL Users mail-list, the issue reported in this post has since been diagnosed and fixed. Marcel Kilgus has posted on his blog how he tested and identified the very small fault in later versions of Minerva (after v1.92) that can c...

I have the same upscaler (at least it looks the same from the outside), and one of by TVs is actually able to display 100% of the QL monitor mode pixels with it. As written above, this, however, varies based on t...

Hi again a) That RGB/SCART cable is probably the best one you'll find for the QL (I use one myself, as do many others here), but I believe that it is designed for RGB as opposed to CVBS. I.e. I don't know whether or not the CVBS signal is passed through. I've since checked the wiring of that QL to S...
